[ELDK] pcap library and tcpdump in ELDK

[Dave Rensberger]

Stefan,

I tried modifying the specfile for tcpdump in a way that looked
analogous to the modifications you guys had made for other ELDK
packages.  So I changed the build section to look like:

 %build
 pushd %tcpslice_dir
 #%configure
 ac_cv_linux_vers=2
 %configure \
     --host=powerpc-linux --build=i386-pc-linux-gnu --with-pcap=linux
 make %{?_smp_mflags}
 popd

 #%configure --with-user=tcpdump
 ac_cv_linux_vers=2 
 %configure \
     --host=powerpc-linux --build=i386-pc-linux-gnu --with-pcap=linux
 make %{?_smp_mflags}

When I run ${CROSS_COMPILE}rpmbuild on this spec file, it still wants to
run configure with "--host=i386-pc-linux-gnu".  Any ideas why?

--Dave

Please take care that you are not using a source rpm from ELDK
distribution. In most cases the .spec in ELDK is modified, for example
to remove all conditions when a test program is executed, not possible
when cross-compiling.

You are compiling for i386, not for powerpc. Try with
--host=powerpc-linux --build=i386-pc-linux-gnu.

Indeed, for libpcap/tcpdump, you will get other errors. You have to run
configure (for both libpcap/tcpdump) with:

ac_cv_linux_vers=2 ./configure --host=powerpc-linux
--build=i386-pc-linux-gnu --with-pcap=linux

Best regards,
